Money means money administration.
Which usually leads to "This is what I want for the money I paid"
Storage is cheap...administration isn't. Coming from a NASA IT guy.

Seriously though we could add a half TB or more fairly inexpensively but the discussion would involve Jim and whether or not it's worth the admin time(his) and expense(mine and probably Jim's) compared to using the free photo post sites.
Maybe Jim/Shannon can weigh in on this.
